Abstract: Embodiments of this disclosure disclose a multi-link communication method and a related apparatus. In a scenario in which simultaneous transmission and reception over a plurality of links is not supported, a multi-link device first sends a first physical layer protocol data unit (PPDU) over a first link, and then sends a second PPDU over a second link through channel contention, where an end time of the second PPDU is not later than an end time of the first PPDU. The method not only ensures fairness of multi-link access, but also can reduce an idle rate of the plurality of links.

Abstract: Embodiments of this application provide a multi-link communication method, an apparatus, and a system that relate to the field of communication technologies, to resolve a technical problem in conventional multi-link communication that an amount of information sent by a multi-link device to a peer multi-link device is large, a process in which the peer multi-link device determines, based on the information, a link that can support simultaneous data sending and receiving as a link that is receiving data is cumbersome, and processing load of the peer multi-link device is heavy. The method includes: generating link grouping information, where the link grouping meets a following characteristic: links belonging to different link groups support simultaneous data sending and receiving; and sending the link grouping information.

Abstract: A STA in a STA MLD sends an information frame on a link corresponding to the station, and the information frame is used to indicate a STA in an awake state in the STA MLD. An AP MLD receives the information frame, and sends a downlink message frame on a one or more links corresponding to a part of or all of STAs in the awake state in the STA MLD.

Abstract: Embodiments of this application disclose a method for determining a data buffer status, and an apparatus. The method includes: A first MLD receives first indication information from a second MLD, and determines, based on the first indication information and a correspondence between an association identifier of the first MLD and a data type supported by the first MLD, a buffer status of bufferable data that corresponds to the at least one data type and that is in the second MLD, where the first indication information is used to indicate the buffer status of the bufferable data. According to the embodiments of this application, a data buffer status in a data type dimension can be determined. The embodiments of this application may be applied to a wireless local area network system that supports a next-generation Wi-Fi EHT protocol of the IEEE 802.11, that is, the 802.11 protocol such as 802.11be.

Abstract: Embodiments provide a multi-link communication method and a related apparatus. A first station generates a radio frame, where the first station is one of a plurality of stations included in a first multi-link device. The first multi-link device includes a first station operating on a first link and a second station operating on a second link. The first station transmits the radio frame on the first link, where the radio frame includes capability indication information, and the capability indication information indicates whether the first station and the second station support simultaneous transmitting/receiving operations. According to the embodiments of this application, communication quality can be ensured.

Abstract: Embodiments of this application relate to the communication field, and in particular, to a multi-link communication method and an apparatus. A STA in a STA MLD sends an information frame on a link corresponding to the station, and the information frame is used to indicate a STA in an awake state in the STA MLD. An AP MLD receives the information frame, and sends a downlink message frame on a one or more links corresponding to a part of or all of STAs in the awake state in the STA MLD, to assist the part of or all of the stations in fast accessing a channel without waiting for a NAVSyncDelay time period.
